How does a bank monetize an international bill of exchange?

A bank monetizes an international bill of exchange by providing financing to the holder of the bill, typically through a discounting process. This involves purchasing the bill at a lower value than its face amount before the maturity date, allowing the bank to profit from the difference when the bill is ultimately paid by the drawee. Additionally, banks may charge fees for processing and managing the transaction, further enhancing their revenue. By offering these services, banks facilitate international trade while generating income from the financial instruments involved.
